Abstract

PCT No. PCT/SE95/01302 Sec. 371 Date Nov. 27, 1996 Sec. 102(e) Date Nov. 27, 1996 PCT Filed Nov. 3, 1995 PCT Pub. No. WO96/14833 PCT Pub. Date May 23, 1996The present invention is concerned with the formation of small particles of organic compounds by precipitating said organic compounds in an aqueous medium containing polymer/amphiphile complexes. The process is preferably used to prepare a readily soluble pharmaceutically active compound.
